Supply air unit, VEKA Technical data VEKA is an air treatment unit with a low overall height and offers the right solution when the installation space is limited. VEKA is available in two sizes. nation of a filter + air heater + fan is only 1000 mm long. Thanks to the small dimensions, VEKA is easily positioned in practically any desired location, e.g. above a false ceiling. VEKA can be supplied with the following combinations of components installed inside the casing: • Filter + fan • Filter + air heater/cooler + fan • Filter + air heater + air cooler + fan A sound attenuator and an...

Supply air unit, VEKA Technical data Components Fan Air heater and air cooler for water The fan is a direct driven radial fan with forwardcurved blades. Its air flow and pressure increase are regulated by controlling the fan speed. It is insulated from the unit casing with a vibration damper and is equipped with a sensor for air flow measurement. The measurement sockets are connected to nipples on the outside of the casing. Accompanying the unit are air distributors that are easily installed on the fan outlets for subsequent functions such as a sound attenuator and electrical heater. Air...
